AUTOMOBILE-WHEEL.

To all 'whom it may concern Be it known that I, CLARENCE W. ToMrirrNs, acitizen of the United States, residing at Brookfield, Linn county,Missouri, have invented a new and useful Automobile- Vheel, of which thefollowing is a detailed description.

My invention relates to improvements in resilient vehicle wheels.

The object of my invention is to produce a wheel of said class having aspring cushion carried on the spokes thereof intermediate of the hub andrim adapted to absorb the vibration caused by travel over an irregularroadbed.

A further object of my invention is to provide telescoping cylinders onthe spokes of a wheel housing a compressible spring adapted toresiliently sustain the weight of the vehicle, and for other purposes tobe hereinafter described and more particularly pointed out in the claim.

In the accompanying drawings, in which like reference charactersindicate similar parts, Figure 1 is a side View of my wheel showing aportion thereof in cross-section; Fig. 2 is a transverse sectional viewof one of the spokes and outer rim; Fig. 3 is a detail perspective viewof the telescoping cylinders and other part-s of the resilient spokes ofmy invention, and Fig. l is a sectional view of a portion of the rim ofmy wheel.

Referring now to the drawings, P indicates the hub of my wheel and R theradial spokes of ordinary construction. Attached to the outer end ofeach spoke is a cylinder C, preferably rect-angular in cross section,

having the head C closing the inner end, the outer end of which isadapted to receive the cylinder A which fits snugly inside cylinder Cand extends substantially half way of its depth. Said cylinder A isclosed at its outer end by the head A. Within said telescoping cylindersis longitudinally carried the corrugated spring B, each end of which isturned laterally to parallel the heads of the cylinders and are providedwith orifices properly positioned to fit on lugs 0 on the cylinder headsto secure said spring in position within said telescoping cylinders. Itwill be apparent that the tend- Specification of Letters Patent.

ency of said spring B is to press the inner cylinder outwardly tosustain the annular frame comprising the felly of my wheel hereinafterdescribed, and as the said cylinders are airtight, it will beappreciated that the air compressed therein will form an air cushionwhich assists the spring B in sustaining the weight of the wheel.

The outer ends of all the inner cylinders C assembled in my wheelstructure are reinforced and held in regular radial position by theannular metallic band N which may be either brazed or otherwise fastenedto each of said cylinders. The felly of my wheel is substantiallyU-shape in cross-section having the channel sides J, to the outer edgesof which is bolted or otherwise secured the rim M, to which is suitablysecured the tire S of any preferred material. On the outer end of theouter cylinder A and preferably cast integral therewith, is the arm Zwhich projects through suitably spaced slots in the inner periphery ofthe felly into the channel F thereof. Said arm is provided with two setsof brackets V and Vv at substantially right angles to the arm. On eachof said sets of brackets is mounted the rollers H and H respectively,the faces of which contact with each other, and the outer roller H bearsupon the rim M and the inner roller H bears upon the inner face of thefelly. It will be appreciated that said construction affords easybearings for the ends of the telescoping spring supported cylinders whenmoving to compensate for the vibration of the wheel. On the innerperiphery of said felly is secured the annular dust cover D comprisingthe overlapping and telesccping sections D and D2.

For the purpose of preventing the spokes and telescoping cylinderscarried thereon from revolving on the rim M, I provide corrugated springbraces T secured on the inner cylinders C at one end and on the sides dof the felly at the opposite, as shown in Fig. 1 of the drawings.

I claim:

A resilient vehicle wheel comprising a hub, radial spokes, telescopingcylinders secured on the ends of the spokes, a corrugated spring carriedwithin said cylinders Q moana secured at its opposite ends to theopposite rotation on said rollers, substantially as detelescopingcylinders, a channeled folly, scribed. roller bearings secured on theouter ends of C W TOMPKINS said telescoping cylinders and carried insaid 5 channeled felly, said rollers contacting with Vitnesses:

the outer and inner rims of said felly, and O. C. POWER, resilientbraces securing said felly against J. FRED PEERY.
